I recently had to implement the function you described. What i did was to have a Runnable checking out if the ScrollView had stopped scrolling by comparing the value returned by getScrollY() when the onTouchEvent is first triggered with the value returned after a time defined by the variable newCheck. See code below (working solution): … Read more
Solution: ((ViewGroup)scrollChildLayout.getParent()).removeView(scrollChildLayout); //scrollView.removeView(scrollChildLayout); Use the child element to get a reference to the parent. Cast the parent to a ViewGroup so that you get access to the removeView method and use that. Thanks to @Dongshengcn for the solution
Mixing some of the suggestions above, and was able to get a good solution: Custom ScrollView: package com.scrollable.view; import android.content.Context; import android.util.AttributeSet; import android.view.MotionEvent; import android.widget.ScrollView; public class VScroll extends ScrollView { public VScroll(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } public VScroll(Context context, AttributeSet attrs) { super(context, attrs); } public VScroll(Context … Read more
Every instance of View calls getViewTreeObserver(). Now when holding an instance of ViewTreeObserver, you can add an OnScrollChangedListener() to it using the method addOnScrollChangedListener(). You can see more information about this class here. It lets you be aware of every scrolling event – but without the coordinates. You can get them by using getScrollY() or … Read more
This works: Rect scrollBounds = new Rect(); scrollView.getHitRect(scrollBounds); if (imageView.getLocalVisibleRect(scrollBounds)) { // Any portion of the imageView, even a single pixel, is within the visible window } else { // NONE of the imageView is within the visible window }
Try this one Note: Here parentScrollView means Outer ScrollView And childScrollView means Innner ScrollView parentScrollView.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { Log.v(TAG, “PARENT TOUCH”); findViewById(R.id.child_scroll).getParent() .requestDisallowInterceptTouchEvent(false); return false; } }); childScrollView.setOnTouchListener(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { Log.v(TAG, “CHILD TOUCH”); // Disallow the touch request for parent … Read more
Just make the top-level layout a ScrollView: <ScrollView xmlns:android=”http://schemas.android.com/apk/res/android” android:layout_width=”match_parent” android:layout_height=”match_parent” android:fillViewport=”true”> <TableLayout android:layout_width=”match_parent” android:layout_height=”match_parent” android:stretchColumns=”1″> <!– everything you already have –> </TableLayout> </ScrollView>
I found a solution that works excellently and can scroll the ListView without problems: ListView lv = (ListView)findViewById(R.id.myListView); // your listview inside scrollview lv.setOnTouchListener(new ListView.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { int action = event.getAction(); switch (action) { case MotionEvent.ACTION_DOWN: // Disallow ScrollView to intercept touch events. v.getParent().requestDisallowInterceptTouchEvent(true); break; case MotionEvent.ACTION_UP: // … Read more
You should use NestedScrollView instead of ScrollView when you’re trying to scroll another view in your parent layout. It’s very similar to ScrollView and part of the v4 support lib: https://developer.android.com/reference/android/support/v4/widget/NestedScrollView.html
